Test Description

The numbers below refer to the step numbers on the diagnostic table.
5. This step tests the system for restrictions.
7. This step tests the following components for the following conditions:

* The pump for internal leaks

Note: Power steering hoses may not look kinked, but have a layer separation causing the inner hose to collapse and restrict power steering fluid flow.

* The power steering pipes and hoses for kinks

8. This step tests the ability of the pump to regulate flow at maximum pressure.
10. This step tests the ability of the pump to regulate flow under normal operating conditions.
12. This step tests the internal components of the pump and the gear.
